To all whom it may concern:

Be it known that I, WALTER E. Corrm, of

Ohio, have invented a new and useful Improvementin Coupler-Shank and Yoke Connections, of which the following'is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a view partly in side elevation and partly in vertical section of a device embodying my invention; Fig. 2 is a planview of the same; Fig. 3 is a view partly in side elevation and partly in vertical section, showing a portion of,the device on a Fig. 4 is a plan view of a portion of the device showing usual Uform, open improved character for greater verticaf depth than sides of the 'rear end means for locking the connecting pin or bolt; Fig.5 is a plan view of the rear end portion 'of the coupler shank and showing a slight modification thereof; and Fig. 6 is'a vertical. section of the rear end portion of the coupler shank,

My invention has relation to means of connecting the coupler shanks of car couplers to draft rigging yokes; and is designed to provide: a simple and convenient form of connection in which the parts can be readily disconnected either by a straight-rearward movement of the a forward movement of the coupler shank,

as hereinafter more fully described.

In the accompanying drawings, the nu-.

meral 2 designates the yoke, which is 'of the at its',forward end. Both-forward ends of the yoke are in the form of enlar ed bosses 3, which are of the'thickness of the arms of the yoke, so as to provide a sub-- stantial bearing ar a for the body of the or olt 4;. Extending foris rounded at its forwar or ledge 5, which whose center is coincident edge to a radius with the center of the pin or bolt l. These ledges or 'flanges are overlapped by upand rearwardly extending --l1ps 6, the upper and lower of the coupler shank,

wardly which are formed at in order to facilitate car repairs,

yoke. and to and whose rear edges are similarly rounded so that the yoke 18 free to have an angular movement relative to the coupler shankmoving-about thepin or bolt 4L asa pivot. The

purpose of the lip and ledge engagement of the shank and yoke is to prevent thetwo arms of'the yoke, which are not connected at their forward ends, from spreading, and

throwing so great a bending movethereby as to cause it to ment upon the pin or bolt bend. I I

The parts cairbe readily assembled, and

the constructlon 1s a very convenient: one in facilitating car repairs.

by a straight rearward yoke, or by a forward movement of the couplershank. This enables the draft gear to be disengaged and dropped down from the car frame without removing the coupler entirely from its p'o- After removing the inn or bolt l, the yoke and coupler can be disengaged either 'movement of the pplication filed December 22, 1911.

lnFigz'b I have shown a slight modification, in which the rear end portion 9 of the coupler shank is of tapered or flaring form. What I claim is i A draft-rigging yoke having uppserf and lower arms; a vertical portion connectin said arms at their rear ends, theq forwar ends of said arms having enlarged bosses of greater vertical depth than the thickness of thearms; pin-holes in said bosses; aiceuplershank adapted to angle laterally with said seat between said bosses and having a pin-hole registering with the-holes in said bosses,-the bosses having integral forwardly-projecting flanges rounded at their forward ends projections having concave vertical'faces on the top and bottom of the coupler-shank adapted to overlie said flanges and prevent spreading of the arms; plane longitudinal bearing surfaces upon shank.
